Question

Sketch a graph of the greatest integer function y=[[cosx]]

Answer 1

the range will have only three values.... -1, 0, and 1...
for:
\(\large 0\le x<{\pi \over 2} \), y=0
x = \(\large \pi \over 2 \), y = 1
\(\large {\pi \over 2} < x< \pi \), y=0

i'm pretty sure u can figure out the values for \(\large \pi < x < 2\pi \)

Answer 2

Thank You!
